1) because you can't actually use it to feed?
Hello, the strip club and all other routes are still under development, this game is only 2 months old.
So, "you can't use it to feed right now".
Sorry if this caused you any frustration, feeding there will be implemented soon.
2) allowed me to still do other things.
You can still feed in the park, do all other events, buy blood from the witch's shop, visit the stores, work etc.
I hope if you come back in the future the game is more to your liking ^____^
